This type of “honeydew” refers to a sticky syrup excreted by the terminal opening in a bug's gut when it eats too much of your plants' sap. Basically, it eats until it pops.

Why do plant leaves turn black?

Improper watering causes plants leaves to turn black and drop prematurely, but this can happen if you water too much, and can also happen if you water too little. Ensure the soil around the plant remains evenly moist at all times, and when the top 1 to 1 1/2 inches of the soil feels dry, you know you're good to water.
